Type 662 Kixcelt Remote Control Pilot Drive Actuator Introduction Introduction Scope of Manual This manual describes and provides installation, operating procedures, maintenance and parts information for the Type 662 Kixcel Remote Control Pilot Drive Actuator.
Description Remote set point control on several Fisher pilot-operated and self-operated regulators can be accomplished with the Type 662. Using electronic control signals to switch its electric stepping motor on and off, the unit turns the pilot adjusting screw changing spring compression to increase or decrease outlet pressure. The design provides smooth, highly accurate positioning with positive position-lock when not in motion. A Type 662 is typically used where remote setpoint control using regulators is required. The Type 662 is highly adaptable into remote telemetry units (RTU’s), programmable logic controllers (PLC’s), and distributed control systems (DCS’s). The features required for integration into these devices are standard.
Specifications Specifications for the Type 662 are listed in Table 1. Refer to the appropriate manual for specifications on the pilot or regulator.

Requires 1 hole panel mount option PM1 for Type 67 regulators and special spring case for other type numbers. For NACE 67AFR applications, consult factory. Spring part number 15A9258X012. SM1020 high torque actuator will work with all spring ranges. Blanking plate option must be ordered with Type 32 pilot and Type 310 regulator.
Installation Recommended installation position for the Type 662 is with the cover vertical as shown in Figure 1. The pilot and actuator should be installed as close to the regulator as practical.
The Type 662 can be pipestand or wall mounted. Use one pipe clamp to mount the actuator on a 2-inch (nominal) vertical pipestand. For wall mounting, utilize two cap screws or bolts to secure the mounting bracket to the wall. It is suggested that wall mounted actuators utilize a uni-strut or another standoff device that will allow sufficient clearance from the wall to allow easy access to conduit entry holes, potentiometers, and DIP switches. This is useful if frequent field adjustments are required. Mounting holes in the bracket are 3/8-inch (9.5 mm) diameter and are on a 2-3/4-inch (70 mm) center to center horizontal hole pattern.
W ARNING If the actuator is being added to an existing regulator installation, the pilot must be disconnected from the regulator and then mounted to the actuator . System pressure should be removed before attempting to disconnect the pilot. The actuator is not designed for submersible service. Do not install in areas prone to flooding. Note It is recommended that calibration and testing of the pilot/regulator to actuator electronic adjustments be performed on a test bench or when actual pressures are not controlling a live system. This can provide for a smoother start up and avoid the chance of making unwanted pressure changes in a live operating system.

1. Attach coupling to actuator shaft with slotted end away from actuator using a .125-inch x .75 inch roll pin and set screw. Be sure that set screw is tightened to flat of actuator shaft. 2. Attach mounting bracket to actuator using four 1/4-20 x .63-inch cap screws. Check orientation of mounting bracket to ensure adequate clearance for conduit access to the actuator 3. Remove existing adjusting screw from pilot or regulator. Find matching (thread size) adjusting screw from kit with a hole in adjusting screw head. Note that some kits may contain more than one adjusting screw, the extras can be discarded. Install a .156-inch x 1.00-inch long roll pin into hole on adjusting screw until it is about half way through. 4. Install new adjusting screw and adjust pilot or regulator spring to approximately one half travel. On Type 32 and 32A pilots, remove the spring case cap off the spring case. This is identified as key #2 in the Type 310/310A instruction manual. With a Type 32 or 32A pilot, you will use the spring case cap as a locknut and will perform steps 5 and 6 before moving spring to half travel. 5. Slide supplied locknut onto the actuator coupling. Slide pilot or regulator into hole on bottom of bracket lining up roll pin in adjusting screw head with slots on coupling.

ronmental conditions and the voltage/ frequency of available line power . To avoid the possibility of personal injury caused by electrical shock, disconnect all power to the actuator before removing cover .
Factory Defaults Pilots, regulators and actuators are shipped from the factory with setpoint spring at approximately half travel and a fine adjustment is necessary to set the zero and span of the input signal or limit switches if manual control is desired. If the pilot or regulator is removed from the actuator and the spring adjustment changed or the actuator shaft position moved, it is necessary to recalibrate the actuator and reposition the pilot or regulator spring. Power Input Input power of 120/240 VAC or optional 28 VDC is connected at terminal block TB1 (Figure 4). Switch SW1 is used to determine whether input power is 120 VAC or 240 VAC. It is important to note position of switch SW1 and adjust before applying power. Also verify correct polarity of field wiring on terminal block locations before applying power to the actuator.
Type 662 DIP Switch Selections Disconnect all power before changing any DIP switch settings (SW1, Figure 5). Refer to Table 4 when making switch selections. Auto/Manual
The actuator can run in automatic mode or manual mode. In automatic mode, the output shaft position corresponds proportionately to the analog input command signal. If using with a Fisher Remote Operations Controller(ROC), the ROC analog output source module is used for the command signal. In manual mode, the actuator corresponds to contact closure for rotation from external pushbuttons or control relays. This selection is controlled by DIP switch #7. If connecting to a ROC, a relay output module or a discrete output isolated module may be used if manual control is desired. An interposing relay can be used with a discrete output source module if desired.

5. There are two modes for loss of signal selection(LOS). D Park in place. D Go to low setpoint. With DIP switch #8 in the down position, the actuator will go to the lowest setpoint (4 mA or 0 VDC) upon loss of the command signal. If switch #8 is in the up position, the unit will park in place upon loss of signal. If power is lost, the unit will fail in the last position.
Note For manual mode operation, leave switch #8 in the down position.
Command
Signal
Selection
This feature allows the actuator to respond to a variety of input signals. The input signals are controlled by DIP switches - #1, 2, 3, 4, and 5, and are selected as follows: 1. If input command signal is voltage, moving switch #4 down will put the actuator in voltage mode. In the up position, the actuator is in current mode. 2. Next select (if in current mode) range of current: DIP switch #1 down selects 4 20 mA. If switch #2 is down, the range is shifted to 4 12 mA. If #3 is down, the range is shifted to 12 20 mA. Note Only one of the first three DIP switches should be in the down position.
3. If voltage mode is selected, moving switch #5 down changes the actuator from 0-10 VDC to 0-5 VDC. 4. Select the actuator rotation direction. For Counterclockwise rotation on increasing input signal, DIP switch #6 should be up. Placing DIP switch #6 in the down position will reverse the actuator rotation (clockwise). This applies to both manual or automatic operation. Note When switching rotation direction from clockwise to counterclockwise (on increasing signal), the limit switches and analog position zero and span must be

1. Only one of these switches may be down. 2. For manual mode operation, leave switch #8 in the down position.
Limit Switches The actuator has four independently set limit switches. Output of the four limit switches are isolated transistors. LS-1, LS-2, LS-3, and LS-4 can be independently adjusted anywhere within the range of operation. The limit switches can be used to cutoff the manual operation signal when lower or upper limits are reached. Limit switches may be directly wired into a Remote Telemetry Unit (RTU), Programmable Logic Controller (PLC), Distributed Control System (DCS) or ROC. If using the limit switches with a ROC as a status indicator, a Discrete Input Source module should be used. The limit switch definitions are as follows:

D LS-2 Upper Limit 1 — Energizes as signal increases and LED turns on and transistor opens. D LS-3 Lower Limit 2 — Energizes as signal decreases and LED turns on and transistor opens. D LS-4 Upper Limit 2 — Energizes as signal increases and LED turns on and transistor opens. Each limit switch may be configured for (N.O.) or (N.C.) operation. Operation over the entire servo range is available for end of travel or position control. DS-1 through DS-4 are LED indicators located above setpoint potentiometers. The LEDs can assist in determining the state of limit switches. A LED on (red) (Figure 4)indicates the limit switch is open. Potentiometers R9 through R12 control limit switch adjustments LS-1 through LS-4 respectively. Use the limit switch settings to control the maximum and minimum range. Clockwise rotation of the corresponding control potentiometer will cause LS-1 and LS-3 to go off and LS-2 and LS-4 to go on. Counter clockwise rotation reverses this action.
Speed Speed of the actuator can be adjusted with the motor speed potentiometer R57, located on the lower printed circuit board (Figure 5). Once the motor speed potentiometer is set, the current limit potentiometer must be set per the instructions in the Torque Limit section.
8
Torque Limit Motor torque of the actuator is adjustable to yield an electrical thrust limiting feature. When the motor torque is exceeded, the actuator will stay in place. It can remain in this position indefinitely without overheating provided the current limiting potentiometer is adjusted correctly. Adjustment is via the current limit potentiometer R62 (Figure 5) located on the lower printed circuit board and the procedure is as follows: With the actuator in motion and operated at the selected speed(within the speed-torque range of the device) slowly turn the current limit potentiometer counterclockwise to reduce current limit. Stop turning when the actuator begins to stall due to not enough motor torque. Next give the current limit potentiometer one full turn clockwise. The current limit adjustment is now complete. Any readjustment of the speed potentiometer will require a repeat of this procedure. Figure 6 shows the torque curve of the SM1010 and SM1020 Kixcels.

Type 662 Setpoints For command signal position input, the actuator zero and span setting for upper and lower setpoints must be defined. For analog control, use terminal block TB2 at positions 3( ) and 4(+) (Figure 7). For a voltage command signal, use terminal block TB2 at positions 5(+) and 6( ) (Figure 7). Install wiring from controller to actuator. Note the controller manufacturer’s specifications on field wiring recommendations from the controller to the actuator. An analog or voltage command signal is applied to the appropriate terminal blocks to establish zero and span setting or upper and lower setpoints. Enter a zero or a low command signal and adjust the low setpoint potentiometer R54, located on the lower printed circuit board (Figure 5), until the desired pressure setpoint is achieved. This established the zero position of the command signal and sets the regulator low signal pressure. Next apply a high signal for establishing the span of the regulator. Adjust the high setpoint potentiometer, R55, located on the lower printed circuit board (Figure 5), until desired pressure setpoint is established. The span of the unit is now complete. Re-check zero, midrange, and span again to verify repeatability. Note that positioning accuracy is +/ .25%.

Note There may be a slight deadband in the linkage connecting the regulator to the actuator . This is normal and can be minimized by using the lightest spring rate available for the regulator selected. Also adjust deadband potentiometer to allow for linkage deadband.
Setting the deadband establishes the actuator servo sensitivity and can be used to accommodate noise on the command signal line, mechanical instability, backlash, etc.. It determines the tightness of the operating servo loop. Potentiometer R56 on the lower printed circuit board will adjust the deadband. This feature is useful when using the command signal to avoid continuous adjustments on continuous control loops and to offset any hysteresis in the linkage.
If the actuator is going to be operated in manual mode, then use upper and lower limit switches as end of travel limits. This prevents actuator from over travel, See Figure 7 for wiring.
If the actuator is going to be operated by a dry contact closure, DIP switch #7 must be in the up position. Figure 7 details how a manual operation must be wired. Upper and lower limit switches must be set to prevent over travel of the actuator and/or over pressure by the regulator.
Isolated Output Feedback Signal The isolated output feedback signal will provide a 4 to 20 mA signal indicating the stem position of the actuator. It is a loop powered feature requiring the analog input’s power to be sourced from the connecting device. The zero and span of the feedback transmitter is adjusted on the lower board as illustrated in Figure 5. The 4mA setpoint is the zero setting and the 20 mA setting is the span.

Type 662 Fisher Remote Operations Controller (ROC) Installation In a typical application (Figure 8), the ROC sends a signal to the drive of the actuator based on a user-entered setpoint. The setpoint is loaded into the ROC on-site or sent remotely from a host computer. A position feedback signal is monitored by the ROC to determine if the setpoint has been achieved. The actuator can be driven by either analog or discrete command signals, giving the user several interfacing options to the ROC. Position feedback is available as an analog signal or up to four discrete limit values. Any of the following signal values can be used to connect the actuator to the ROC: Drive Command:
4 to 20 mA 0 to 5 VDC Contact Closure (1 increase, 1 decrease)
Position Feedback:
4 to 20 mA, externally powered Contact Closure (2 upper limit, 2 lower limit)
ROC
actuator moves proportionally to an increase or decrease in the output signal supplied by the ROC. Either direct or reverse action can be selected by DIP switches located in the actuator electronics. Figure 9 shows the typical connections for current and voltage command signals.

Drive Command
The position of the actuator output shaft is determined by the amount of time the contacts are closed. The ROC determines the amount of time to keep the contacts closed based on either a position input received from the actuator or a pressure input supplied by a pressure transmitter.

Figure 8. ROC-to
for Discrete
The actuator command terminals are self-powered, therefore the ROC switch contacts must be �dry�. When the ROC306 is used to provide the command signal, one set of contacts must come from the auxiliary power relay (labeled NO) and the other from the field wiring discrete output (labeled DO). For other ROCs, either the discrete output isolated module or the discrete output relay module can be used.
Type 662 ROC
Pressure Feedback If more precise setpoint control is required, the ROC can be connected to an electronic pressure transmitter located downstream of the regulator as shown in Figure 13. The pressure transmitter provides for closedloop control and allows the ROC to compensate for the regulator’s inherent droop.

All ROCs can support inputs from analog pressure transmitters, and the ROC306 and ROC312 can support HART-compatible pressure transmitters as well. All ROCs are capable of implementing one or more PID control loops.

Feedback
Position Feedback Connections Both analog and discrete position feedback signals are available from the actuator. The analog signal is generated by a potentiometer located in the actuator that must be powered from a ROC analog input (Figure 11). The analog feedback signal can be used in conjunction with either an analog or a discrete command (output) signal. The discrete feedback signals are provided by four limit switches, two designated as upper limit and two as lower limit, as shown in Figure 12. The limit switches establish four limits which can be monitored by four discrete inputs on the ROC (ROC306 is limited to two discrete inputs). The limit switches use isolated transistors which require power from the ROC. ROC
While position feedback would not be required when using pressure feedback, it can be useful in determining if the pressure transmitter, actuator, or regulator is within calibration limits. Once the system is calibrated, the pressure feedback signal can be compared to the position feedback signal and a relationship can be established. If over time the relationship between the two signals changes by more than a pre-determined amount, an alarm can be generated to notify an operator. ROC

Motor Doesn’t Appear to Work
Guide POSSIBLE
CAUSE
Power isn’t on; Turn power on. DC power polarity reversed. Command signal not received or not in range; Check DIP switch settings. Manual operation signal contact closure not received; Input signal not wired correctly. Motor at end of travel limits; Readjust endpoints and recalibrate. Insufficient DC voltage from power supply.
Transformer Feels Hot
Current limiting pot not set correctly; Recalibrate current limit pot.
Lower PC Board Operation
Green LED always lit when driving with increasing signal. Yellow LED always lit when driving with decreasing signal. Both green and yellow LED’s are on at limits. Both green and yellow LED’s are off when at setpoint.
No Output Feedback Signal
Check wiring terminations and polarity. Measure supplied voltage. Make sure analog circuit is loop powered from controller or RTU.
Motor Chatters or Vibrates in Place
End of travel limits are reached; Readjust limit switch pots. Current limiting pot are not set correctly. Motor over operational torque specifications. Speed adjustment too high for torque requirements; Lower speed. Regulator at end of adjustable range; Disconnect regulator from actuator and set both the regulator and actuator at mid-range. Deadband pot set to tight; CCW rotation of pot increases sensitivity.
